Ultrasonic cleaning is an ultrasonic cavitation application technology

One, without the technology to control the cavitation generated by ultrasound, it cannot be controlled.

Even if you copy and clean our products perfectly, if you don’t master the basic technology, you won’t be able to handle problems when they arise, and that won’t make your product a product.

Without daily management methods and guidance for inspecting and verifying equipment capabilities, customers will not be able to produce with confidence and trust in the capabilities of the equipment.

In the field of ultrasonic cleaners, manufacturers that actively apply degassing technology or manufacturers of ultrasonic deburring equipment have virtually disappeared from Japan because other companies do not understand the theory of cavitation control, which is the basis of ultrasonic cleaning and the foundation of ultrasonic deburring.

A comparison with our company is shown below.

Differences from Other Companies

• Existence of cavitation control theory (aka shibano theory)

1988 Announced This is the basic theory of ultrasonic cleaning. If not mastered.

We can’t do the basic design. No other company can. It comes down to experience and intuition.

• Control of ultrasonic cavitation generation position

Cavitation is a technology to determine the location of cavitation generation and to use it efficiently. Cavitation is generated at a specific location and the object is placed at that location.

• Control of ultrasonic cavitation generation density

If the cavities are sparse and hard to hit the target area, what’s the point?

The technology is to increase the density of the occurrence. This is a technology to increase the generation density.

• Control of ultrasonic cavitation impact force

If the cavity impact force is too small, it cannot be removed; if it is too large, it cannot be removed.

destruction. I have published and am familiar with this basic formula.

 

• 　　Control of Ultrasonic Cavitation Cavity Types

Depending on the gas content in the liquid

that the cavities generated by the Chonpas are drastically altered.

Discovered in the late 1980s!

It then became the harbinger of rapid innovation in ultrasonic cleaning.

Below is the core of shibano’s theory

• Gas content 20 ppm or more in dissolved oxygen

(primarily all cleaning agents and solvents other than water)

　　　Only visible bubbles are generated Ultrasonic waves are eliminated 99.9% on the diaphragm surface

Ultrasonic bubbling phenomenon, not ultrasonic cleaning!

Still more than 90% of washer manufacturers,

I believe the bubbles are ultrasonically generated bubbles, and I’m designing one!

• Gas content Less than 2ppm in dissolved oxygen

Generates globular nebula shaped cavities

Efficiently produces strong positive and negative shock waves.

　　This cavity is the first time that a precision, powerful ultrasonic cleaning system has been used.

　Ultrasonic deburring becomes possible.

Other than our company, there are other manufacturers who understand this theory and use cavitations.

is not found.

• Difference between ultrasonic oscillators

Our ultrasonic wave oscillator is the world’s only simultaneous multiple-wave oscillator that uses 25 KHz as its fundamental frequency and oscillates at 50 KHz, 75 KHz, 100 KHz, 125 KHz, and so on, multiplying the fundamental frequency by 25 KHz each. This device is designed to generate cavities over as wide a range as possible, and to avoid complications in designing the optimum liquid depth for each frequency, it is placed on the fundamental frequency and only 25KHz is considered in the design. There is an optimum liquid depth for each frequency. It is meaningless to create various frequencies without the technology to control the cavities.

 

• Difference between ultrasonic diaphragm and vibrating element
• Successful development of ultrasonic cleaning vibrating element for deburring

Until last year, we had been using general-purpose 25KHz 70W elements (used at 50W) from Japan and other Asian countries, including for deburring, but in response to customer requests, we began to find that strong vibration sometimes resulted in destruction. The element is mounted on an M10

This is a phenomenon in which a stud bolt gouges through a SUS304 plate, and it is obvious.

It shows the limitations of conventional cleaning elements.

The new device has been in use since January of this year after a one-year test period at 25 KHz and 150 W (used at 120 W). The new device has improved the deburring performance (sound pressure more than twice as high). In addition

The new technology is expected to more than double the life of the product. Of course, this is unique to our company, and we will continue to develop it further.

 

• Diaphragm manufacturing method

We are almost the only company in Japan that has delivered ultrasonic diaphragms of 3600W or higher for practical use. We have delivered many 14400W ultrasonic diaphragms.

Why is it that we are the only company that manufactures this product? The reason is that the ultrasonic diaphragm manufacturing method is special, and we are the only company that can manufacture the ultrasonic vibration element attached to the diaphragm after it is assembled.

This is because shibano succeeded 20 years ago in developing a technology to inspect each piezoelectric element (up to 72 elements at 3600W) while oscillating it, and we can safely guarantee the performance of our products to our customers.

　　　Without precise outgoing inspection, there is no guarantee of performance, and without a guarantee of performance, there is no product. The inspection for deburring is more precise than that for cleaning.

　As a 　result, we are the only ultrasonic cleaning and deburring manufacturer that can inspect, repair, and diagnose problems with the diaphragms we deliver.

A strong deburring diaphragm is subjected to powerful shock waves. A simple SUS304 with hard chrome plating will become tattered and unusable within six months. We use a special surface treatment followed by a hard chrome plating.

The titanium titanate treatment increases the hardness more than 10 times and prevents the surface from erosion.

　It is the only measure of its kind in the world.

 

• Differences between ultrasonic cleaning tanks

Even if you attach a powerful ultrasonic transducer to a stainless steel tank, you cannot perform powerful precision cleaning. Even if you buy our core equipment, it is not possible to perform powerful precision cleaning.

A cleaning tank that can control cavitation and avoid unnecessary air contamination is needed.

• Basics of cleaning tanks for ultrasonic cavitation control

The depth, width, and depth of the tank must be matched to the frequency of the ultrasound in millimeters. The ultrasonic wavelength is a function of temperature. Accurate temperature control is also necessary. Cavities will generate heat. This heat generation must also be addressed. Have you designed these basics?

Without this, not only can cleaning and deburring not be performed, but also

The powerful diaphragm is also very fragile.

It is out of the question for deburring that the depth of the liquid changes when the object is inserted.

 

• Ultrasonic tank, liquid shower room, rectification room (2 locations), storage tank

　　One ultrasonic tank consists of a horizontal shower chamber to prevent air from entering the liquid surface, two rectifying chambers to stabilize the ultrasonic cavitation control and prevent low-frequency squeaks, and a reservoir to prevent air from entering the liquid, which is an important measure. This is the result of ultrasonic theory. This is the result of ultrasonic theory and the conclusion of actual performance. If any one of them is missing, the result will not be achieved.

Where is the company that 　　understands this?

• degasser

By “continuous vacuum degassing,” ultrasonically generated cavities are dramatically transformed into myriad clusters of spherical cavities. Deaerators are important equipment for the creation of strong cavities (globular nebulae to microvacuum nuclei).

 

The maintenance of continuous and stable continuous degassing capability of any deaerator is

Required.

The actual cleaning materials can be contaminated in a variety of ways. Not only fine particles and burr dust, but also sometimes oils, abrasives, fingerprints, mold release agents, various ions, surfactants, etc. Surfactants, etc.

We are a manufacturer of degassing equipment for all cleaning solvents, acids, and alkalis, as well as water. We know all the solutions. We have experience with all types of degassing equipment.

These are essential for ultrasonic cleaning and deaerating equipment for deburring that can be used on the factory floor. Only our technology, which we have developed, manufactured, and marketed for the past 20 years, can provide this service.

 

• Ultrasonic Deburring and Cleaning

Our technology has a proven track record in ultrasonic powerful precision cleaning, and we are the only company in the ultrasonic cleaning market to have been the driving force behind the development of this technology.

I have continued to do so. It will be the same in the future.

We will spread ultrasonic deburring technology as a general-purpose deburring technology throughout the world.

［The difference between cleaning and deburring.]

　　There is a difference between cleaning and deburring. It is also a consequence of ultrasonic theory.

　　Simply put, the temperature is raised for cleaning and cooled for deburring.

　　　I know this simple difference, and I know exactly why.

How many copy manufacturers are there?

[Commodity group].

　　We have standardized our product line for deburring and posted them on our website.

 

 

From the above brief presentation, it can be seen that

　The difference between 　us and other companies is obvious.
